Explanation:

Osteoarthritis is the most common form of arthritis, characterized by cartilage degeneration accompanied by changes in neighboring bone structures. The most affected are the joints of the hands, knees, coxofemoral (connection of the thigh with the hip) to the spine.

Obesity is a risk factor for this since the extra weight presses the joints, wearing away the bone tissue.

In most patients, there are no factors that justify osteoarthritis. Perhaps subtle anatomical abnormalities, such as small irregularities in the joint surface, lead to cartilage wear. Athletic exercise, when neither excessive nor associated with trauma, does not predispose to illness. On the contrary, obesity, repetitive physical efforts and sports with impact are risk factors. On the other hand, conditioning through aerobic exercise can reduce symptoms
